At an under water depth of 400 feet, the pressure is `10 atm`. What should be the mole fraction of oxygen in dibing gas for partial pressure of oxygen in the mixture to be 0.2 atm, the same as in air at 1 atm

A

`0.2`

B

`0.02`

C

`0.1`

D

`0.4`

Text Solution

Verified by Experts

The correct Answer is:
B
`P_(O_(2)) = X_(O_(2)) xx P_(T)`
`X_(O_(2)) = (0.2)/(10) = 0.02`
